[User] Crée un workflow n8n pour: Telegram RSS Autoposter This workflow monitors multiple RSS feeds, detects new posts, rewrites them using AI, and sends the formatted output to your Telegram account. It helps you keep your Telegram feed active with clear, polished, and ready-to-publish content — all fully automated. How It Works A scheduled trigger runs every 30 minutes and loads all RSS feed URLs from an n8n Data Table. Each feed is fetched, and only the most recent item is selected. The workflow checks whether this post has already been processed. If it’s new, the link is stored in a second Data Table used for deduplication. A Groq LLM rewrites the article text so it stays within Telegram’s limits and has clean, readable formatting. The final message is sent to your Telegram account. Requirements Groq API key Telegram b

**Analyse du besoin**
Cette solution répond à un besoin fréquent de curation de contenu automatisée. L'objectif est de transformer des flux RSS bruts en contenus Telegram polissés et prêts à publier. Le workflow doit gérer plusieurs défis : éviter les doublons, reformater le contenu pour Telegram, et maintenir une qualité éditoriale constante. La fréquence de 30 minutes est judicieuse pour rester réactif sans surcharger les APIs.

**Choix techniques**
Le Data Table n8n est excellent pour centraliser les URLs RSS de manière dynamique, permettant d'ajouter/supprimer des sources sans modifier le workflow. L'utilisation d'un modèle IA pour la réécriture est pertinente car elle standardise le ton et adapte le format aux contraintes Telegram (longueur, lisibilité). Le trigger Schedule est approprié pour cette périodicité régulière. L'API Telegram Bot offre une intégration robuste et native.

**Architecture**
Le workflow suit une logique séquentielle efficace : récupération des sources → fetch RSS → sélection du dernier item → vérification anti-doublon → reformatage IA → publication Telegram. Cette architecture modulaire permet un debugging facile et une maintenance simplifiée. La gestion d'état pour les doublons nécessite probablement un stockage persistant (base de données ou fichier).

**Points d'attention**
La gestion des erreurs est cruciale : flux RSS indisponibles, limites d'API IA, échecs Telegram. Il faut prévoir des retry mechanisms et des fallbacks. L'anti-doublon doit être robuste, possiblement basé sur les GUIDs RSS ou des hash de contenu. Attention aux quotas API (IA et Telegram) et à la qualité du prompt pour garantir une réécriture cohérente. Considérer l'ajout de filtres de contenu pour éviter la republication de contenus inappropriés.

J'aimerais ajouter une validation automatique de la qualité des images générées avant de les sauvegarder

[Assistant]
<thinking>
Pour améliorer la qualité du workflow, il faut intégrer un système de contrôle qualité. Cela implique d'ajouter un nœud d'analyse d'image AI après la génération pour évaluer la pertinence et la qualité visuelle.
</thinking>

**Modifications appliquées:**
Ajouter un nœud HTTP Request vers une API d'analyse d'image (comme Google Vision AI), puis un nœud IF pour filtrer les images selon un score de qualité minimum, et rediriger les images non conformes vers une nouvelle génération avec un prompt modifié.

Peux-tu modifier le workflow pour qu'il génère des liens avec une date d'expiration personnalisable ?

[Assistant]
<thinking>
L'utilisateur veut contrôler la durée de validité des liens partagés. Il faut modifier les paramètres de l'API Dropbox pour inclure une expiration et permettre à l'utilisateur de la configurer.
</thinking>

**Modifications appliquées:**
Ajouter un nœud 'Set' pour définir la date d'expiration, modifier le nœud HTTP de création de lien pour inclure le paramètre 'expires' dans l'API Dropbox, et ajouter un input pour que l'utilisateur puisse spécifier la durée.

Est-ce qu'on peut surveiller les avis clients et leur note moyenne en plus des prix ?

[Assistant]
<thinking>
L'ajout de surveillance des avis nécessite d'étendre l'extraction de données. Les avis peuvent influencer la stratégie pricing donc c'est pertinent pour le workflow.
</thinking>

**Modifications appliquées:**
Enrichir l'extraction IA pour capturer les notes et commentaires clients, ajouter des champs pour stocker ces données, et créer de nouvelles conditions d'alerte basées sur les variations de satisfaction client.

**Symptôme**: Les données dans la notification sont 'undefined'
**Attendu**: Valeurs correctes affichées
**Réel**: 'undefined' partout

[Assistant]
<thinking>
**Symptôme**: Le workflow ne produit pas le résultat attendu.

**Trace du flux**:
1. Vérification des données en entrée
2. Suivi de la transformation à chaque node
3. Comparaison avec l'output attendu

**Hypothèses**:
- Mauvaise expression d'accès aux données
- Node mal configuré
- Données manquantes en entrée
</thinking>

## 🔍 Diagnostic

**Problème identifié**: Mauvais chemin d'accès aux données ($json.data au lieu de $json.data.items[0])

**Analyse du flux**:
1. Vérification des données à chaque étape
2. Le problème se situe dans le traitement des données

**Solutions**:

### Option 1: Corriger l'expression
Vérifier que le chemin d'accès aux données correspond à la structure réelle.

### Option 2: Ajouter du logging
Insérer un node Set ou Code pour inspecter les données à chaque étape.
